I had a 268/272 duration .455 lift purpleshaft in my 360 that worked great. Little rumble at idle but nothing radical. Make sure you change your valve springs to the ones that match the cam. 392 gen III hemi on E-85 727 trans Dana 60 10.02@134

Just not enough compression. Would work nice in a 10 to 1 340 though. 392 gen III hemi on E-85 727 trans Dana 60 10.02@134

The MP 268/272 is a great all round cam for a low compression, street-driven 360, with good torque and enough power to run 12's in the quarter in a light car with headers and halfway decent gears.
